The convicted killer of four University of Idaho students is making headlines again, but this time from behind bars. Bryan Kohberger, the 30-year-old former Ph.D. student in criminology, has submitted a series of handwritten grievances in which he alleged that other prisoners at the Maximum Security Institution in Idaho are threatening him every day.

People obtained documents which reveal that Kohberger had requested a transfer from J Block to B Block. J Block is a “tier” that is used for “high profile and high risk” inmates, including those on death row, while B Block is “quieter.” In his letter, Kohberger said that he is being harassed with “minute-by-minute” verbal attacks. Inmates have also allegedly threatened to “rape him in very graphic ways.”

Kohberger claims that the threats began only two days after he was placed in J Block. He reportedly filed another grievance about a week later after he heard an inmate say, “I’ll b— f— you,” and another inmate tell him, “The only a– we’ll be eating is Kohberger’s.” The prison guards confirmed they heard profanities being directed at Kohberger but did not remember the specifics of the language.

“As I continue the SPI phase, I wish to discuss if I may be transferred to another ad-seg setting,” he wrote in the letter, in which “SPI” is prison slang for “administrative segregation” or protective housing to protect a prisoner from threats. “Tier 2 of J Block is an environment that I wish to transfer from if possible. I request transfer to B Block immediately. I wish to speak with you soon.”

Kohberger added in the letter that he has not been “flooding or striking.” Both actions are forms of prison discipline, usually to protest something. “Flooding” is when an inmate plugs the sinks or toilets with soap, toothpaste, and other materials to cause water damage. “Striking” could include not doing work, violence, or other misconduct. State prison officials have not publicly acknowledged if they plan to move Kohberger, and records show he is still in J Block as of Wednesday.

A Target for the Murder of Four Students

Kohberger’s life in prison has been no picnic. His earlier jailhouse records revealed that other inmates often taunted him, even as he was speaking to his mother on video calls. One prisoner called Kohberger a “f—ing weirdo.” Another inmate said that he would have attacked Kohberger “had it not been for what was going to happen.”

But many experts point to the subject of his awkward demeanor and lack of social skills as described in the court documents. His “piercing stare” and his social naiveté, they say, has only made Kohberger an even bigger target. Add to that the notoriety of his crime and, according to some prison consultants, Kohberger was almost bound to have a bull’s-eye on his back in jail. “High-profile offenders nearly always have a target on their back,” a prison consultant told People. “In Kohberger’s case, his personality makes him stand out even more.”

Kohberger’s life since his conviction has changed. He has lost weight since he’s been incarcerated for the past two and a half years. He was placed in Idaho’s most secure prison, which also includes death row inmate Chad Daybell, where some of the state’s most violent inmates are located. The threats have led some to compare him to the likes of Jeffrey Dahmer, a serial killer who also endured years of abuse before he was killed in prison in 1994.

Some prison experts have warned that Kohberger could meet a similar fate if his grievances continue to be ignored. “There is also the matter of what happens to a prisoner, once a target is on his back, should that prisoner continue to have grievances go unresolved,” said another prison expert. “The prison system as it stands today is rife with inmate-on-inmate violence and victimization.”

As of now, Kohberger remains in J Block, where he is expected to live for the rest of his life in prison with no parole. Prison officials have declined to comment on his security status, citing safety and security. But Kohberger’s complaints make it clear that the convicted killer, already living under the weight of his crime, is also living in fear of those around him.

Will Kohberger be moved? It remains to be seen. What is clear, however, is that his notoriety and reputation as a creepy weirdo have traveled well with him into prison. And could very well continue to make him a target for the rest of his days behind bars.
